To make sure it wasn't any udev background processing, I cut out all the non-essential udev rules.
I was left with just this:
# ls /etc/udev/rules.d 20-names.rules 40-basic-permissions.rules 40-permissions.rules 80-programs.rules 85-ifupdown.rules 90-modprobe.rules
NOTE that I explicitly removed the network device renaming rules -- the hang still occurred, so this is not a problem with device renaming.
It must simply be a module loading issue.
